Linux系列（一）给CentOS7.9 安装vncserver

***本文只介绍，在centOS 系统安装vnc 服务端，windows 系统的vnc客户端不作介绍。仅提供文末截图。 ***
先看下系统版本号：

cat /etc/redhat-release

检查是否安装了vnc

yum list installed | grep vnc

完全卸载vncserver

sudo yum -y remove tigervnc-server
rm -rf /home/centos/.vnc
rm -f /tmp/.X11-unix/X1
rm -f /tmp/.X11-unix/X2
rm -f /tmp/.X11-unix/X3
rm -f /tmp/.X11-unix/X4
rm -f /tmp/.X11-unix/X5
rm -f /tmp/.X11-unix/X6
rm -f /tmp/.X11-unix/X7
rm -f /tmp/.X11-unix/X8
rm -f /tmp/.X11-unix/X9
sudo rm -rf /root/.vnc
sudo rm -rf /etc/.X11-unit
sudo rm -rf /etc/.X*-lock
rm -rf .vnc
sudo systemctl disable vncserver@:1.service
sudo yum remove tigervnc-server
sudo find /etc -name "vncserver" -o -name "tigervnc" -type d -exec rm -rf {} +

重新安装vncserver

yum install vnc vnc-server 

yum install tightvnc-server

开放端口号5901

iptables -I INPUT -p tcp --dport 5901 -j ACCEPT 

检查是否装有GNome桌面， 如果没有，就安装

yum grouplist
yum groupinstall "GNOME Desktop"

启动vncserver

vncserver :1
